build: Update flatpak build and organize folder structure

Flatpak doesn't need to build meson or a patch for ninja and meson to
work properly:
https://github.com/flatpak/flatpak/issues/607
https://bugzilla.gnome.org/show_bug.cgi?id=774368
273e2460aa

This patch updates this and improves the folder structure with a
build-aux folder to clear up the root folder.
